Our application for the transputer was switched over to DSP boards which
were at the time more powerful. TI was pushing the DSP's and the ultrasound
machines already used DSP's for signal processing. There was also a long
delay between the earliest transputers and the more powerful ones. Our
setup used 25MHz transputers.

I stand corrected...I gave up cars to get into computers, so it's been a
while. I think I still have the factory shop manual for the AMC Rebel at
home though, as well as enough Motor and Chiltons manuals to cover most
anything between 1954 and 1973.

Externally, practically nothing. Internally, the Sorcerer II has somewhat
different memory decoding, to accomodate 3 rows of 4116's instead of 2, and
they're all socketed. There's a DIP switch to select type and number of
banks, which was done by solder links on the original.
The video timing is also different, and it's easier to get a stable picture
at 50Hz on the Mk.II; one of the poles on the 4-way DIP switch controls
US/UK setting.
Some of the signals on the 50-way expansion interface are slightly
different. There's an MEMORY OFF input so an external device can switch
off the internal RAM. The RSET signal is derived slightly differently,
too.
The Mk.II has fixed the hardware bug in the RS232 (on the Mk.1, the gate
signal to switch from cassette to RS232 was wrongly applied so the RS232
was forced to the wrong logic level when the cassette was selected).
Some of the layout is a little different to accomadate the changes, the IC
number has changed of course, and a few parts of the circuit are done with
(parts of) different ICs.
They're still the same clock speed (2.106 MHz), and (apart from the
differences above) the same machine.

Here's a message I figured someone on the list might be able
to help with. I have a Dilog board in my MicroVAX II but don't know
enough about it to answer his question.

If I recall the models correctly, all but the Monza had just two of the
Webbers, including the turbo-charged version. I believe the Monza was the
model with the 4 carbs and there were problems keeping them synced but it
was still a very nice engine. Sturdy, compact and lightweight. The gearbox
was a bit of an oddity though. If I had the space for one, I wouldn't mind
having another, as I had a '60 model.

The other side is even if you want to spend there are few NOS boards
out there and fewer have much performance.

Likely. Then again I set those things up in my sleep.

Thanks for the info... I only work with them for a lving. ;)

No. No. I retired an old P133 server that had a Wide SCSI card in it..
With the 33mhz FSB there was little hope of using all the performance
of the SCSI-W nor the really fast disk 7200rpm disk hooked to it. With
VLB or EISA your likely talking a 486DX4/133 maximum and they
are even slower. I know I have a 5x86/133 with VESA and the best
I see on that one is maybe 30mb/sec and that the burst rate not
an average.

That and the best data rate will be 8-10mb/sec. ISA isn't fast.
Win95 if you have the OEM disk has drivers for some pretty old and
oddball stuff.
Maybe the point I'm making is just getting them going is often all that
can be asked. Trying to go for maximum smpoke is often not worth
it as recent hardware is cheap and far faster.

Rich,
I have a s***load of STD BUS boards and DOCS including 4 or 5 complete
systems with 8" disks. Alas, no hard drive based systems. If there's any
specific info, you're looking for, I'd be glad to look it up for you?
Unfortunately, I don't have a scanner or digital camera so bear with me :-(
The 7805 is a SBC that may or may not need any additional support cards.
They were mostly used in industrial or dedicated controllers and in fact
many are still in use today. Most of those boards (although not all) have
the processor, serial I/O, RAM, ROM, and timing circuitry all on one board.
Being controllers, there were a wide range of IO options available.
Everything from ADC/DAC converters, 16, 32, 48, 64 bit parallel interfaces,
OPTO 22 and relay drivers, temperature sensors, DISK controllers, etc...
Certainly the two additional cards that you have fit that category.
With all the IO options, they make great platforms for home automation
projects.
Most of the external cards have jumpers that can be used to configure the
address range (ports) for the cards. Most cards would work with any ports as
long as there wasn't an addressing conflict. With a range of 255 ports, the
system was very flexible.
I don't recall for sure but, I think STD standard only requires GND, +5,
+12, and -12 volts. If that's the case, you should be able to wire a regular
PC power supply to the backplane. A full rack which could be 20 or more
cards will certainly suck some power but the few cards that you have would
be well within the capacity of a small PS.
If you trace the lines from the 1488 and 1489 chips to the header connector,
you should be able with a little experimentation figure out how to connect a
dumb terminal. If not, I'll look it up for you.
As far as software, most of the controllers either had the application
burned in ROM or they would boot from an external disk (often CPM). The
BIOSs may be specific to a particular variant of the OS so, not all of them
will work together. IE: A microsys BIOS will probably not work with a DEC
version CPM. A prolog BIOS may not work with a microsys boot disk, etc...
Let me know what specific info you need.
See ya,
Steve

With that kind of failure rate, one has to wonder if there's some kind
of underlying problem other than the Adaptec boards.

I'd have to go back and check the tech manuals to be sure but I believe the
main difference was the amount of memory on the main board. There were a
few other minor differences in the boards but nothing really major as I
recall.
I have a bunch of new manual scans I just need to finish cleaning up and
then I'll place them on my Exidy site. http://www.trailingedge.com/exidy/
Now if I could just find the S100 expansion box and some drives. *wishing
hard* :)
